Abstract

The replacement of a nonlinear MIMO system by a linear system plus a nonlinear noise source was discussed. The optimized measurement strategy was proposed to measure the nonparametric frequency response function (FRF). The measured MIMO system was restricted to a Wiener-Hammerstein structure to trace the influence of the linear dynamics on various parts of the approximation. The results show that the bias and the nonlinear noise on the FRF depend on the applied input signals.
